Comparative expression profiling reveals the role of the hot pepper apoplast under drought conditions

Abstract

Drought stress is the most important limiting factor of crop cultivation around the world and stress conditions will modulate the expression of many genes that play a significant role in the plant growth and development and to stress adaptation. The apoplast is a dynamic environment subject and considered as a ‘key information bridge’ between the environment and cells. In the present study we aimed to measure the changes in the expression levels of genes by RT-qPCR studies.Analysis shown the down-regulation of Peptidylprolyl isomerase and Pin II type protease inhibitor and there observed the huge increase in the expression of Pectinesterase and Alpha L fucosidase under treated conditions. These changes in the expression level of proteins under stress conditions implicate their possible role in stress tolerance and would prove to be useful for protein phenotyping.
